I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

  1. Performance-critical methods and auto vectorization for SIMD-enabled processors

    There should be convenient way to mark certain methods as performance-critical, e.g. with some attribute. JIT compiler should use better optimization for such methods. These optimizations must include auto vectorization with SIMD instructions, like in Visual C++. Like with /Qvec-report in C++, there should be some way to ensure that compiler understood code and can vectorize it. Current vector types are not enough; they are not convenient for FFT, FIR, dot product and other non-graphical calculations. Since C# is high-level language, developers should not waste time with manual optimizations.

    • Support "natural sorting" / SORT_DIGITSASNUMBERS via CompareOptions

      The C++ function, CompareStringEx ( https://msdn.microsoft.com/en-us/library/windows/desktop/dd317761.aspx ) has a dwCmpFlags option for SORT_DIGITSASNUMBERS: Treat digits as numbers during sorting, for example, sort "2" before "10".

      This option should be exposed as a member of the CompareOptions Enumeration ( https://msdn.microsoft.com/en-us/library/system.globalization.compareoptions.aspx ) so that it can be used in managed code instead of needing to do a DllImport of Kernel32.DLL which requires UNSAFE / Full Trust.

      • Add a way to Get the Progress percentage of Extracting a zip file in System.IO.Compression.

        Currently I cant Update a Progressbar with percentage (unlike with downloading) when Extracting a zip file. I would like to make this possible below.
        ```cs
        ZipArchive zar = ZipFile.OpenRead(Application.StartupPath + "\\ILSpy_Update.zip");
        /*
        Not Sure how I can get it to fill the Progress bar. I think I would need some help here on this part.
        */
        zar.ExtractToDirectory(Application.StartupPath + "\\Update\\");
        zar.Dispose()```

        • TPL async task.ConfigureAwait() should have option to inherit the stack trace from original thread

          When we await an async task, the continuation Thread does not appear to inherit the call stack from the originating Thread. This causes us problems when we use the System Diagnostics Tracing as the call stack does not represent the logical flow throw the application.

          • WebBrowser. Compatibility Mode Edge by default

            The WebBrowser control should run in edge mode by default or at least let us control this in the browser through a property. By default the browser seems to be running in IE 7 compatibility mode and most new websites do not render correctly.

            From what I can tell the options to correct his are:
            Insert tags in the web pages. This is impossible as I don't control the internet. Change a registry key, also impossible as click once setup does not allow this.

            Right now my only option is to use a 3rd party browser like cefSharp which adds…

            • CRC32 Helper Class

              Many applications that communicate with low-powered hardware need a way to verify the received data. CRC32 is a well-known, lightweight check value which is better suite to verify short data.

              .Net already has an implementation of this check value with (System.IO.Compression.Crc32Helper, System.IO.Compression, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089) but this class has an internal ac cess modifier and can't be used by user code.

              My proposition is to make the Crc32Helper class public.

              • Sepcify table name for multiple recordsets

                When you return multiple recordsets from a store proc, it will be nice if we can specify the custom table name for each record set and access the tables via table name than index. In this way code can be dynamic and lot easier. The current hack is provide one extra table for recordset to table name but it is not neat. Depending on the index and prior knowledge can cause lot of bugs.
                The following should be done
                1) When multiple recordsets are returned from the storeproc, the SP developer can tag each recordset with a table name (ex:…

                  Sometimes we use clases that are not in the intelligence and not in our namespace. Why don't white it with help of the intelligence and auto import it

                  • Linq - add, update, delete statements

                    I think it would be simple the idea to add, update and delete objects based on the Enumerator<T>
                    C# Example

                    Insert into:
                    var i = 0;
                    var a = from d as MyType in MyEnumerableType
                    where d.IdProp = 1
                    insert new MyOtherType(i++,d.IdProp,d.Prop1) {Prop2 = d.Prop2} into MyOtherEnumerableType; //-> performing over the enumerator of both objects

                    Update:
                    var i = 0;
                    var a = from d as MyType in MyEnumerableType
                    where d.IdProp = 1
                    set d.Prop1 = "Value different than before", d.BooleanProperty = False

                    Delete:
                    var a = from d as MyType in MyEnumerableType
                    where d.IdProp = 1

                    • Auto-create Controller Actions from data entered into JavaScript/JQuery Ajax methods

                      A great feature of many IDEs, including VS, is that you can define a function on the fly and automatically create a method stub for it.

                      Wouldn't it be great if this could be done when you are making Ajax requests to the server?

                      For example, say you wish to send data to an action using JQuery's $.post() method:

                      You type $.post("MyController/MyAction", {data: "myData"}); into your front-end code, this new feature would then give you the option to auto-create an action "MyAction" in controller "MyController" with a string paramater "data" and a default return type of say, ActionResult.

                      I'm still…

                      • Add GetParentDefinition() Reflection APIs to allow walking the override chain of members

                        Currently, it's really hard to implement a correct algorithm that gets the parent definition of a MethodInfo, PropertyInfo, or EventInfo representing a member override. A naive implementation is bound to contain bugs regarding overloading, shadowing, generics, and overrides with non-matching accessibility. The only support Reflection offers for the not so uncommon use case of walking the member override chain is the MethodInfo.GetBaseDefinition() API, which can be used to check whether two MethodInfos are part of the same override chain (they are if they have equivalent base definitions). However, even using GetBaseDefinition one can easily make mistakes (e.g., forgetting to take…

                          My PC consists of an Asus GTX STRIX 1080 (8GB GDDR5X Ram) and my monitor is Asus PB287Q which is 4k.

                          • Covariant read-only collection interfaces

                            I'm reopening my old request for "Typesafe immutable collections". We now have immutable collections but they are not covariant.

                            Please add covariant read-only interfaces for lists, sets and dictionaries.

                            Coming up with a good name might be an isssue since now both ReadOnly* and Immutable* prefixes are used by BCL while something like ListView sounds like a class from WPF. Maybe ReadableList ?

                                • Add CanTellLength and CanSeekBackwards to System.IO.Stream

                                  • Add CanTellLength property to the System.IO.Stream:

                                  public virtual bool CanTellLength {
                                  get {
                                  try {
                                  var length = this.Length;
                                  return true;
                                  } catch {
                                  return false;
                                  }
                                  }
                                  }

                                  • Add CanSeekBackwards property to the System.IO.Stream:

                                  public virtual bool CanSeekBackwards => CanSeek;

                                  • Why
                                  Working with System.Net.Http.StreamContent I found that it caches the request in memory before sending the HTTP request if the length of the stream is unknown. And to perform the check if the length is known it uses CanSeek property - it mixes completely different concepts.
                                  I came up with conclusion:
                                  - The stream can tell…

                                  • PFX support for Hosted Build Controller

                                    Have the hosted build controller support signed pfx natively. Perhaps allowing us to store the pfx in Azure KeyVault.

                                    • Expose Collation Info of SQL Server Result Set via SqlDataReader

                                      The exact collation of each string field should be publicly available. The properties can be added to the DataTable returned by the GetSchemaTable() method, or they can be added as individual properties and/or methods of the SqlDataReader class, or a combination of both. The properties are:
                                      1) LCID
                                      2) SqlCompareOptions
                                      3) collation_name (e.g. Latin1_General_100_BIN2)

                                      The "LCID" and "SqlCompareOptions" values already exist in the "SqlDataReader" class, but are private or internal ( http://referencesource.microsoft.com/#System.Data/System/Data/SqlClient/SqlDataReader.cs,277 ). These would make sense to put into the GetSchemaTable output.

                                      The "collation_name" value is necessary due to the combination of "LCID" and "SqlCompareOptions" not being enough to…

                                        • Dynamic class

                                          Include support for dynamic class in .net.

                                          This should allow the developer to take existing classes and either add more properties to the class in a new class, or remove properties.

                                          This will allow the developer to create DTO classes from original classes, cutting away the properties he wants, but maintaining the ones he wants as well.
